Trouble migrating 2008R2 VM to 2012R2 Host. Intergrated Components fail

Hello All
We have a new 2012 R2 server with Hyper-V.
I'm trying to migrate the VMs from 2012 Std Host but when I move a 2008 VM it seems to struggle to load the intergrated components or it's having trouble with the built in components from the 2008 VM.  It appears to be the same with our 2011 SBS VM
too.  The 2011 fails to even create the virtual NIC within the VM.
I've successfully moved two 2003 VM's without issue. 
Help please?
Thanks
Daren

Hi Daren,
Try to do Mark's solution and you can try to do as follows:
Shut down all Hyper-V virtual machines on the host then stop the Hyper-V Virtual Machine Management
service
net stop "Hyper-V Virtual Machine Management"
Copy all virtual machines you want to migrate to WS2012R2 Hyper-V host then
Import Virtual Machine…
Install integration services.
Hope this will be helpful.

  • The vm and host networking components failed to negotiate protocol version '4.0'

    Hi,
    I have the problem that when I start a VM with windows server 2012 on a hyper-v v2 host, it takes very long till the VM get bind the static or dynamic ip adress. I tried both, static and dynamic. In every case I see at the event viewer the following error:
    the vm and host networking components failed to negotiate protocol version '4.0'
    After a few minutes the VM gets bind the IP an everything works fine. But at the next time I reboot the machine the same failure appear.
    Trying to use legacy network adapter results in the same problem. After this I tried to export the vm to a hyper-v v3 host. At first boot time
    the problem didn't appear and the vm get's bind the ip adress without problems. Then after upgrading the integration services to hyper-v v3
    version the same problem appears but without register it in the event viewer.
    Does anybody know how I can fix this problem?
    Kind Regards,
    Marcus

    Hi,
    A MS KB records an issue when you run Windows 8 or Windows Server 2012 based Virtual machine in Windows Server 2008 or in Windows Server 2008R2:
    http://support.microsoft.com/kb/2744129
    There is a Microsoft update in this KB, you may install this KB in your Windows Server 2008 R2 and check the result.
    While about this issue after you migrate the guest VM to Windows Server 2012 host, will it still has such error message after you remove all network adapters of the guest VM?
    Install Windows update for the Hyper-V host, after that upgrade Integration service for the guest VM again to check the result.
    For more information please refer to following MS articles:

  • The VM and host networking components failed to negotiate protocol version '5.0'

    I have been searching for a fix for this issue for sometime.
    The VM and host networking components failed to negotiate protocol version '5.0'
    and
    The VM and host networking components failed to negotiate protocol version '4.0'
    this error have been posting on the host server 2008 R2, with a hyper-V running server 2012 R2, which is the eval version vhd from Microsoft.
    I have tried the patch on the server 2008 R2 host and the nic delete and rescan option with varied reboots and such between each step of the process just to try every possible combination.
    The error persists. Are there any other suggested solutions for fixing this problem. Also the drivers have all been updated along with the system firmware.
    thanks,

    The hotfix states Server 2012 in the VM. You stated Server 2012 R2 in the VM.  MSFT is very precise in this language - Server 2012 != Server 2012 R2.
    Two distinctly different releases of Windows Server.
    In this case the N = the running release of Hyper-V.  In this case your Hyper-V Server at release version 2008 R2.
    The +2 = the current version of Windows.  In this case that is 2012 R2.  Two releases ahead of the version of the hypervisor you are running.
    I tossed in the link to Ben Armstrong's blog article as that is the ONLY (and still definitive statement) support statement regarding this configuration.  He posted that article at my request after many folks posting in this forum with strange behavior
    in this configuration.
    "supported" in this context means that if you call CSS, you will be told the following: 'yes, you have errors in the event log.  We will not fix that.  This is an unsupported configuration.  But that does not block the OS in the
    VM running.  If you want the errors to go away, we suggest you upgrade your Hyper-V Server to 2012 R2.  That configuration is supported.'
    That said, it can impact other functionality of the VM that rely on Integration Components in the VM and the Services of the hypervisor.  There is most likely small things that will not work.

  • Can I safely uninstall intergrated components from 2008R2 VM

    My SBS2011 DC is running on a 2012R2 Host that's was a member server
    I've run into an issue with replication because I needed to reboot the host and of course the host comes up before the DC so I've removed the host from the domain so it's now a standalone Workgroup box
    My trouble is the virtual network adapter won't install on the DC VM, keeps telling me 'Microsoft Virtual Adapter is not configured correctly'
    I've unzipped the CAB file from the IC disk and tried to manually install the driver for the adapter but no
    I assumed an upgrade of the intergrated components would fix it but it reports the components are up to date.
    Help please?
    Thanks
    Daren

    Hi Daren,
    In the VM open device manager  --> view --> show hidden devices --> delete all devices under Network adapters .
    Then shutdown the VM and remove the network adapter from VM settings of 2008R2 VM .
    If the issue persists , try to add a legacy NIC to check if the issue will arise again .

  • Converting Debian 7 ESXi 4.1 to 2012R2 host :

    Hi,
    I'm trying to convert Debian 7 VM to hyper-v using MVMC 2.1. In GUI wizard on  Virtual Machine section, under Operating System there is shown Other Linux (x64) instead of Debian 7. Debian version 5 is show correct (for olders dis. VM), as Debian GNU/Linux
    5 (x64). I suppose that is reason for Warning on Summary screen in Wizard :
    Warning (s):
    1. The operating system of the VMWare VM is NOT SUPPORTED. This does not prevent conversion, but no support is provided for this conversion.
    The tool is running on target Hyper-V 2012R2 host with .NET 4,5 installed along with Visual C++ Redist 2012 update.
    After continuing conversion (ignorring the warning above), conversion stops after sucessfuly snapshot creation on ESXi host with following error :
    "One or more errors occurred. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Accelerators.Mvmc.ScxSshWrapper_x86.dll' or one of its dependencies. The specified module could not be found."
    I also reboot Hyper-V host but same error appears every time .
    Thnx.
    Update#1: I have to install both x64 and x86 Visual Studio Redist 2012 Update 4 to avoid stop error on .dll. The main warning (VM not supported stays).
    Now I have new problem, during Uninstall Tools step conversion stops with message: Host does not Exist. When open error log: there is :
    VERBOSE:    Attempting to establish an SSH connection.
    07/23/2014 17:06:56 +02:00  [3]  VERBOSE:    Finished creating snapshot of the source virtual machine
    07/23/2014 17:06:59 +02:00  [3]  DEBUG:    Caught ManagedSshFacadeException trying to open SSH connection: ErrorCode=0xC0040202, Message=Host does not exist
    07/23/2014 17:07:04 +02:00  [3]  VERBOSE:    System.AggregateException: One or more errors occurred. ---> Microsoft.Accelerators.Mvmc.ScxSshCommon.ManagedSshFacadeException: Host does not exist
    Update#2: Host unknown error was because Debian wasn't in internal DNS of Hyper-V host, after adding Linux to DNS error went away (it seems to use DNS name to establish SSH connection). However after that I received errors in same "Uninstall Tools"
    step about connection rejected because of too many failures for root account... I saw that in the "Connection Step" of wizard I was unable to enter Password for Root account for selected VM, (I don't know is that by design for Linux VM's). So I beleive
    that error is reffering to that stage of setup. Anyhow  I decided to manually remove VM Tools , shutdown VM and convert VM in offline mode. Now VM is working on Hyper-V, and I hope that this few hours of troubleshooting will help someone. After all there
    are still some questions :
    1. Why Warning : 1. The operating system of the VMWare VM is NOT SUPPORTED - is displayed for Debian 7 which is on supported list of guest OS
    2. Why online conversion didn't work, and why password for root account in VM (under Connection portion of wizard) could not be entered.
    If anyone have answers to above question please share your knowledge.
    Regards,

    MVMC 3.0 did not include any new features for Linux so I doubt the results will be different. We did add support for RHEL 7, CentOS 7 and Oracle 7.
    For your questions:
    1 - Since VMWare does not have a specific choice for Deb 7, newer versions may by now, we throw the warning as we cannot determine what version of Linux you are trying to convert when you select [Other Linux X64]. Deb 7 is supported by MVMC as
    we've tested it and know it works. Other Linux distros may work as well that are not supported but they have not been tested.
    2 - Most likely you did not have the VMWare VM running when trying to do the online conversion or it could not be resolved in DNS by the vSphere server. When running the MVMC tool did you notice if it had a DNS name associated with it when you selected
    it in VMWare?
    The MVMC requires the VMWare VM to be in a running state and resolvable in DNS by both the MVMC system and the VMWare vSphere server to verify the root password and remove the VMWare tools. As you have stated, you can remove the VMWare tools manually
    and run the MVMC and it will work as well. If you leave the VMWare tools installed and do the conversion we disable the VMWare tools on the Hyper-V VM once booted. They are still there but should not be in a running state and you can remove them if desired
    at this point.
    Regards,
    -Steve

    No entry is made on the cluster log of the destination node. 
    To me this means the nodes cannot talk to each other, but I don’t know why.  
    They are on the same domain.  Their server names resolve properly and they can ping eachother both by name and IP.

  • Oracle Grid11g On Linux el5 Connection to host as user failed

    Hi,
    I have oracle grid 11g control running on Linux.
    I have configured it to monitor a target (oracle 10g database) on solaris 10, but I'm unable to schedule backups.
    I get error *" Connection to host as user failed "*.
    I am providing the oracle user account details for the solaris .
    I tried logging in to normal Enterprise Manager for the oracle 10g database and the host credentials was validated.
    Can anyone advice why the same host credentials failed on grid?
    Please help.

    If youre adding the host in preferred credentials, have you
    1. Configure the database first via > targets > database > configure
    2. Are you using a proxy?
    3. Did you try with the domain name prefixed on the OS user?
    4. Whats in the emoms trace? If nothing much, switch to debug mode and try again and you may catch something else.
    5. worst comes to worse,throw in a windump or tcpdump trace while you run the connect to see if theres anything at an OS level youre missing, OS errors back to the GC will just manifest themselves as "could not connect to host as user..." the dump will show you what they are but this is last case.

    c. act as part of the operating system
    d. allow log on locally
    e. adjust memory quotas for a process
    f. replace a process level token
    3. We have also verified that this user and group have not explicitly been denied the log on privileges in:
    a. deny log on as a batch job
    b. deny log on as a service
    4. Additionally, we have also tried setting the console service to run as the local user we want to set as the host user credentials (originally set to run as the local system account).
    I have been unable to verify yet that the user or the admin or ora_dba groups have been granted privileges under the create global object policy, but I have only found one post in the forums suggesting this and am unclear if this is a requirement or not.
    I have also seen it recommended to input the host user name as <domain_name>.<name_of_computer>\<user_name>. However, I saw one post that recommended this only if the server was also running AD. I have never installed on the same server as AD and I normally only need to define my host credentials as <domain>\<user>, so I am assuming that this is the case. I'm I correct here?
    I have never had a problem setting these credentials on Windows Server 2008 with Oracle at 11g using the common suggestions listed above, on the forums, and in the installation guide. Any ideas where I can look next or what I have missed? Are there any other policies that might be being pushed to this server that I should look for? Thanks.

    AilD, Thanks. That's pretty much where we started other than our user was a local user rather than a domain user. From what I understand, the formatting of the user name really shouldn't matter, unless you have a domain user you wish to use that happens to have the same name as a local user, where Oracle will assume that you are referencing the local user if you fail to include the domain. No big deal for us since we are using a local user, there shouldn't be any issues with using just the user name to identify the user. Perhaps I am focusing too much on the way the user is identified in OEM.
    Does anyone have experience configuring Oracle in abnormally secure environments? In this case, the onsite DBA is segregated from IT and unsure of what policies are being pushed to his servers. Perhaps there are other polices I haven't already listed that may be causing havoc in setting the host user credentials?

  • NLB converging problem VM1 on 2008R2-host VM2 on 2012R2-host

    Hello
    We are in the process of uppgraring our Hyper-V enviroment from 2008 R2 to 2012 R2.
    We migrate the VM's from 2008 to 2012 on volume at a time and now I have run into a problem with NLB between
    two VM's, VM1 is on 2008-host and VM2 is migrated to 2012-host. Both VM's run OS 2008 R2.
    The migration steps we use is:
    Stop the VM on 2008-host
    Copy VHD to 2012 Cluster storage
    Create new VM on 2012-host (from Failover Cluster Manager)
    On VM2 I added a second NIC and set the same IP as the original.
    I have Enabled MAC adress Spoofing and tried setting a static MAC on the NLB NIC but without any luck.
    But the VM is stuck in status Converging.
    I have read most threads I can find on this issue and tried most suggested solutions.
    My question now is if there are any problem in running NLB on VM's when they are on different Hyper-V versions (2008R2/2012R2, both is Datacenter Edition) 
    /Anders

    Hi,
    Which NLB mode you are using? If you are using the IGMP mode you need to configure your switch to allow the NLG data through.

  • Best practices for installing Win 10 under Hyper-V on Server 2012R2 host

    Yeah, yeah, I know I could probably get my answers after spending 10 hours reading hundreds of isolated threads here.  I've already put in about 2 hours, and I'm exhausted.  Plus, this site does not have a very sophisticated search function.
    I want to install Win10 as a VM on my Server 2012R2 machine.  I am not currently hosting any other VMs, so my first decision was whether to try it using Hyper-V or VirtualBox.  I started with VirtualBox, but I ran into two problems: networking
    and video.  Also, VirtualBox itself seems to have some issues with failing to install the extension pack.  So now I think I'll give Hyper-V a shot.
    I found some blog posts from last year providing guidance on setting up Hyper-V for Win10, but given the rate of change of this beta OS, I expect there are many new "features" that can be mitigated against by specific settings on the VM.
    Some specific questions:
    1. Generation 1 or Generation 2 in the Hyper-V setup?  The blogs I've seen say to use Gen1, but provide no justification.  Perhaps because they are using Win8 as the host?  I am using 2012R2.
    2. Does the Win10 ISO file need to be continually available to the VM, or is it only used in the initial installation?
    3. How do I get the VM to access the GPU card, which has lots of memory, over the useless onboard video chip which only has 8MB and no 3D instruction set?  This was a dealbreaker with VirtualBox.
    4. I anticipate many issues with networking, but I'll start with this: I have dual onboard NICs going into a managed switch.  Should I just give one physical NIC to the VM and let the host have the other?  I think I'm going to have some issues
    with DHCP IP address assignment, but we'll see.  Any best practices here would be helpful.
    Thanks.

    >1.
    I'd use Gen 1, that is a BIOS type boot, but that's just because I've had
    less trouble than with Gen2 VM's.
    >2.
    Only during install, refresh, reset, or sfc.
    >3.
    No virtualization solution does it easily, but there is RemoteFX if you can
    get a Windows 10 client to use it.  I've never tried.
    http://social.technet.microsoft.com/wiki/contents/articles/16652.remotefx-vgpu-setup-and-configuration-guide-for-windows-server-2012.aspx
    >4.
    That's what I would do (assigning one NIC to the VM, and one the host).  If
    both are receiving an IP address right now from DHCP, they will continue to
    do so the new way unless you have a managed switch that would prevent more
    IP addresses.  It's hard to tell...

  • Upgrading Hyper-V Server 2008R2 Cluster to 2012R2

    I have a Hyper-V Server 2008R2 (free 'core' version) cluster that I would like to upgrade to Hyper-V Server 2012R2 (same 'core' version).  I found
    this document that seems to outline the process, however I have the following questions...
    Any reason this process won't work on the "core" version of Hyper-V.  i.e. "Microsoft Hyper-V Server 2008R2".  I currently have a 2-node 2008R2 HA cluster with "core" servers and am looking to migrate that cluster
    to the "core" version of 2012R2.
    Is there no way to do this "in place", meaning without a dedicated target server?  It seems like the process assumes you just have extra servers sitting around that can act as targets.  I suppose I could shuffle VMs off one cluster node,
    evict that node from my current cluster, rebuild it with 2012R2 core, add it to a new cluster as the only node and carry on with the process outlined here?  Once all VMs are on the new "cluster" of one 2012R2 node, I would destroy the original
    cluster, rebuild those machines with 2012R2 and add them as nodes to the new cluster?
    Any reason the "Failover Cluster Manager" tool, version 6.1, I've been using to manage my 2008R2 environment won't work to do the migration?  Or are there new 2012 tools I need to have installed on my workstation.  Remember, since this
    is the "core" version I can't manage anything from the server.
    Thanks,
    Todd

    Here's an update on what happened...
    The first VM that failed turned out had 1 snapshot, which I know is a no no, but I generally never snapshot servers so it didn't even occur to me to check.  So that's why the migrated VM wouldn't boot.  When I recreated the VM manually and pointed
    to the VHD file it obviously didn't include the AVHD content so it booted the server into a 2 month old state.  That led to the domain problems since the AD server account password had changed sometime in the last 2 months.  I tried a bunch of fixes
    but the only thing that finally worked was to remove the server from the domain and re-join.  Of course, that then broke Citrix, but that's getting off-topic.
    The second VM that failed was because for some reason a CSV that it relied on was not migrated over and I didn't notice that in that in the report.  And then I couldn't find any way to bring that CSV in after the fact.  I re-ran the pre-migration
    and it still didn't show it.  Of course this is my biggest volume at 800GB.  So I then re-mapped one of my old cluster nodes back to the LUN (after removing the new node), brought up the lost CSV, copied the VHD file on it to external media, brought
    the old cluster down again, the new one up and was going to blow away that LUN and create it as a new CSV on the new cluster.  Of course, when I went to go create the CSV it showed my LUN available for storage and I just had to add it and all the data
    was brought with it.  So 2 hours of copying for nothing!  I'm not at all sure what happened with this problem, but it seems either rebooting the old cluster node or the new one jarred things lose.
    Just wanted to report back saying everything is going again.  And also to vent about how poor and riddled with pitfalls this migration is.  The snapshot issue is ridiculous, how hard would it be for the tool to check for that and then throw an
    error in the migration report?
    For anyone that needs to upgrade from 2008 to 2012, good luck!
